Hi all,
I have a GT with the leather seats and find myself adjusting them constantly every time I drive the car. I can't find that "just right" position. Each time I make a change, I think, "that's it". A few miles later I'm making more changes.

Anyone else find the seats a little hard to get comfy in? For me there seems to be too much arch midway up the backrest, making my back curve in ways it doesn't like to.
